You know what the meaning of marvel world
Mean
X-men
Mis msrvel
Sheald
Avengers
Doctor strange
Spider-Man
guardians of the galaxy
Thor...
.....
I suggest that Mc enter early in marvel world meet mis marvel and nick fury
So Mc could access space travel....
Also you could add that in Japan
There is also mutated people like xmen so you could add hero academy element later...
Or hidden ninja villages... Like konoha....
